Chicago Cubs’ left-hander Mike Montgomery broke into the major leagues in 2015 as a member of the Seattle Mariners. At the age of 25, Montgomery started 16 games for the M’s, pitching to a 4-6 record and 4.60 ERA. Even though Montgomery tossed two shutouts that year, he still recorded a below average ERA+ of 83.
The following season, 2016, Montgomery was assigned more of a bullpen role. The 26-year-old southpaw made just two starts in 32 appearances for the Mariners. Montgomery thrived in that position, recording an ERA of 2.34 and an ERA+ of 174.
